The drop bear (sometimes dropbear) is a hoax in contemporary Australian folklore featuring a predatory, carnivorous version of the koala. This imaginary animal is commonly spoken about in tall tales designed to scare tourists. While koalas are typically docile herbivores (and are not bears), drop bears are described as unusually large and vicious marsupials that inhabit treetops and attack unsuspecting people (or other prey) that walk beneath them by dropping onto their heads from above. [1] [2] [3] [4] [5] [6]
Although the drop bear originated as a hoax, observers have noted its similarities between to Thylacoleo , a hypercarnivorous marsupial from the Late Pleistocene. [7]
The origin of the drop bear myth is unknown. It has been attributed to a sketch in The Paul Hogan Show in which koalas jump out of the trees and attack a man. However, others say it began as a scary story for children, or as a trick played on soldiers visiting Australia for training. [7]
A 1967 article in Army , the Australian Army's newspaper, mentions "a dreaded Drop Bear", [8] and a 1976 article about an army base refers to "the legends and stories of drop bears and hoop snakes that supposedly originated there". [9] Other early appearances in print include a Royal Australian Navy News article in 1978 [10] and a classified advertisement in the Canberra Times in 1982. [7] Dropbears, an Australian band, formed in 1981.
Stories about drop bears are generally used as an in-joke intended to frighten and confuse outsiders while amusing locals, similar to North American "fearsome critters" such as the jackalope. [11] Tourists are the main targets of such stories. [12] [13] These tales are often accompanied by advice that the hearer adopt various tactics purported to deter drop bear attacks—including placing forks in the hair, having Vegemite or toothpaste spread behind the ears or in the armpits, urinating on oneself, and only speaking English in an Australian accent. [5] [14]
The website of the Australian Museum contains an entry for the drop bear written in a serious tone similar to entries for other, real, species. The entry classifies the drop bear as Thylarctos plummetus and describes them as "a large, arboreal, predatory marsupial related to the koala", the size of a leopard, having coarse orange fur with dark mottling, with powerful forearms for climbing and attacking prey, and a bite made using broad powerful premolars rather than canines. Specifically it states that they weigh 120 kilograms (260 lb) and have a length of 130 centimetres (51 in). [15] The tongue-in-cheek entry was created for "silly season". [16] [17] The Australian Museum also established a small display in the museum itself, exhibiting artefacts which it stated "may, or may not, relate to actual drop bears." [17]
Australian Geographic ran an article on its website on 1 April 2013 (April Fools' Day) purporting that researchers had found that drop bears were more likely to attack tourists than people with Australian accents. [18] The article was based on a 2012 paper published in Australian Geographer, and despite referencing the Australian Museum entry on drop bears in several places, images included with the Australian Geographic article were sourced from Australian Geographer and did not match the Australian Museum's species description. [5] [15] [18]
The drop bear hoax, using a polar bear, was humorously referenced in an advertisement for Bundaberg Rum. [19]
In the Discworld novel The Last Continent by Terry Pratchett, drop bears inhabit the continent of Fourecks, [a] a land portrayed as a parody of Australia. This version of the drop bear tale shows the animals with well-padded backsides to cushion their fall. [20]
Australian Chris Toms and New Zealand musician Johnny Batchelor formed a band named Dropbears in 1981. [21]
Observers have noted similarities between the drop bear and the specimen Thylacoleo . [7] Like the drop bear, Thylacoleo (also called the "marsupial lion") was a hypercarnivorous marsupial found only in Australia.
A 2016 Nature study of claw marks in caves concluded the marsupial lions could climb rock faces as well as trees. [22] [23] In a 2018 study, paleontologists conjectured them to be ambush predators that would leap on unsuspecting prey. [24] Incisions on bones of the extinct kangaroo Macropus titan suggest Thylacoleo fed in a similar way to modern cheetahs, using their sharp teeth to slice open the ribcage of their prey, thereby accessing the internal organs. They may have killed by using their front claws as either stabbing weapons, or as a way to grab their prey with strangulation or suffocation. [25]
Diprotodon is an extinct genus of marsupial from the Pleistocene of Australia containing one species, D. optatum. The earliest finds date to 1.77 million to 780,000 years ago but most specimens are dated to after 110,000 years ago. Its remains were first unearthed in 1830 in Wellington Caves, New South Wales, and contemporaneous paleontologists guessed they belonged to rhinos, elephants, hippos or dugongs. Diprotodon was formally described by English naturalist Richard Owen in 1838, and was the first named Australian fossil mammal, and led Owen to become the foremost authority of his time on other marsupials and Australian megafauna, which were enigmatic to European science.
The koala, sometimes inaccurately called the koala bear, is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae. Its closest living relatives are the wombats. The koala is found in coastal areas of the island's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, dark nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (8.8–33.1 lb). Its fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations are possibly separate subspecies, but not all researchers accept this.
The thylacine, also commonly known as the Tasmanian tiger or Tasmanian wolf, is an extinct carnivorous marsupial that was native to the Australian mainland and the islands of Tasmania and New Guinea. The thylacine died out in New Guinea and mainland Australia around 3,600–3,200 years ago, prior to the arrival of Europeans, possibly because of the introduction of the dingo, whose earliest record dates to around the same time, but which never reached Tasmania. Prior to European settlement, around 5,000 remained in the wild on Tasmania. Beginning in the nineteenth century, they were perceived as a threat to the livestock of farmers and bounty hunting was introduced. The last known of its species died in 1936 at Hobart Zoo in Tasmania. The thylacine is widespread in popular culture and is a cultural icon in Australia.
The jackalope is a mythical animal of North American folklore described as a jackrabbit with antelope horns. The word jackalope is a portmanteau of jackrabbit and antelope. Many jackalope taxidermy mounts, including the original, are made with deer antlers.
Megalania is an extinct species of giant monitor lizard, part of the megafaunal assemblage that inhabited Australia during the Pleistocene. It is the largest terrestrial lizard known to have existed, but the fragmentary nature of known remains make estimates highly uncertain. Recent studies suggest that most known specimens would have reached around 2–3 m (6.6–9.8 ft) in body length excluding the tail, while some individuals would have been significantly larger, reaching sizes around 4.5–7 m (15–23 ft) in length.
Thylacoleo is an extinct genus of carnivorous marsupials that lived in Australia from the late Pliocene to the Late Pleistocene, often known as marsupial lions. They were the largest and last members of the family Thylacoleonidae, occupying the position of apex predator within Australian ecosystems. The largest and last species, Thylacoleo carnifex, approached the weight of a lioness. The estimated average weight for the species ranges from 101 to 130 kg.
The term Australian megafauna refers to the megafauna in Australia during the Pleistocene Epoch. Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested.
A goanna is any one of several species of lizard of the genus Varanus found in Australia and Southeast Asia.
Thylacosmilus is an extinct genus of saber-toothed metatherian mammals that inhabited South America from the Late Miocene to Pliocene epochs. Though Thylacosmilus looks similar to the "saber-toothed cats", it was not a felid, like the well-known North American Smilodon, but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to convergent evolution. A 2005 study found that the bite forces of Thylacosmilus and Smilodon were low, which indicates the killing-techniques of saber-toothed animals differed from those of extant species. Remains of Thylacosmilus have been found primarily in Catamarca, Entre Ríos, and La Pampa Provinces in northern Argentina.
Carnassials are paired upper and lower teeth modified in such a way as to allow enlarged and often self-sharpening edges to pass by each other in a shearing manner. This adaptation is found in carnivorans, where the carnassials are the modified fourth upper premolar and the first lower molar. These teeth are also referred to as sectorial teeth.
In Australian folklore, the Queensland tiger is a creature said to live in the Queensland area in eastern Australia.
The mammals of Australia have a rich fossil history, as well as a variety of extant mammalian species, dominated by the marsupials, but also including monotremes and placentals. The marsupials evolved to fill specific ecological niches, and in many cases they are physically similar to the placental mammals in Eurasia and North America that occupy similar niches, a phenomenon known as convergent evolution. For example, the top mammalian predators in Australia, the Tasmanian tiger and the marsupial lion, bore a striking resemblance to large canids such as the gray wolf and large cats respectively; gliding possums and flying squirrels have similar adaptations enabling their arboreal lifestyle; and the numbat and anteaters are both digging insectivores. Most of Australia's mammals are herbivores or omnivores.
Thylacoleonidae is a family of extinct carnivorous diprotodontian marsupials from Australia, referred to as marsupial lions. The best known is Thylacoleo carnifex, also called the marsupial lion. The clade ranged from the Late Oligocene to the Late Pleistocene, with some earlier species the size of a possum, while the youngest members of the family belonging to the genus Thylacoleo reached sizes comparable to living big cats.
Quinkana is an extinct genus of mekosuchine crocodylians that lived in Australia from about 25 million to about 10,000 years ago, with the majority of fossils having been found in Queensland. Four species are currently recognized, all of which have been named between 1981 and 1997. The two best understood species are Q. fortirostrum, the type species, and Q. timara, a more gracile form from the Miocene. The other two species, Q. babarra and Q. meboldi, from the Pliocene and Oligocene respectively, are only known from a few poorly preserved bone fragments. The name Quinkana comes from the "Quinkans", a legendary folk spirit from Gugu-Yalanji mythology.
Palorchestes is an extinct genus of large terrestrial, herbivorous Australian marsupial of the family Palorchestidae, living from the Miocene through to the Late Pleistocene. Like other palorchestids, it had highly retracted nasal region suggesting that it had a prehensile lip, as well as highly unusual clawed forelimbs that were used to grasp vegetation.
Wakaleo is an extinct genus of medium-sized thylacoleonids that lived in Australia in the Late Oligocene and Miocene Epochs.
In North American folklore and American mythology, fearsome critters were tall tale animals jokingly said to inhabit the wilderness in or around logging camps, especially in the Great Lakes region. Today, the term may also be applied to similar fabulous beasts.
Muribacinus is an extinct genus of thylacinid that lived during the middle Miocene in what is now northwestern Queensland, Australia. It was described in 1995 from remains collected at the Riversleigh World Heritage Area. Only one species is known, M. gadiyuli.
Australian mythology stems largely from Europeans who colonised the country from 1788, subsequent domestic innovation, as well as other immigrant and Indigenous Australian traditions, many of which relate to Dreamtime stories. Australian mythology survives through a combination of word of mouth, historical accounts and the continued practice and belief in Dreamtime within Aboriginal communities.
Microleo attenboroughi is a very small species of the Thylacoleonidae family of marsupials from the Early Miocene of Australia, living in the wet forest that dominated Riversleigh about 18 million years ago. The genus Microleo is currently known from a broken palate and two pieces of jaw, containing some teeth and roots that correspond to those found in other species of thylacoleonids. The shape and structure of the blade-like P3 tooth, a premolar, distinguished the species as a new genus. It was found in Early Miocene-aged deposits of the Riversleigh fossil site in Queensland, regarded as one of the most significant palaeontological sites yet discovered, and named for the naturalist David Attenborough in appreciation of his support for its heritage listing. The anatomy of Microleo suggests the genus is basal to all the known thylacoleonids, known as the marsupial lions, although its relative size prompted one discoverer to describe it as the "feisty" kitten of the family.
